Installing Windows 7
Boot your PC from your Windows 7 DVD and then follow the steps to install Windows 7. During setup you can either install Windows 7 to a separate partition or wipe out a previous version of Windows. Whichever way you do it, Windows will automatically handle the formatting.
After Windows 7 is set up, and you've booted into the desktop, type activate
in Start Menu Search to bring up the Activate Windows utility and type in your product key to activate Windows.
Then, run Windows Update, download any pending updates, reboot as needed, and repeat ... until there are no more updates.
That's it, you're done ... with installing Windows 7.
Look in Device Manager for any yellow splats ("!"). If you see one, for say the 'xyz' wireless adapter, then you need the 'xyz' wireless adapter driver for your specific version of Windows 7, (32-bit or 64-bit). Download and install it and then reboot. Repeat until there are no more yellow splats.
Then, test each of the hardware devices such as USB/eSATA ports, memory card slot, LAN, Modem, VGA/DVI, PCMCIA/CardBus/ExpressCard slot(s), Fingerprint reader, etc. If one of them isn't working, download and install the driver/software for your version of Windows 7.
I usually download and install all applicable updates/patches.
If you see something else you'd like to have on that IBM/Lenovo page, and it's designed to work with your specific version of Windows 7, (32-bit or 64-bit), download and install it.
You're now ready to install, setup and tweak all of your defenses, ('anti'-virus/-malware/-evil/-annoying type stuff).
And finally, once you get it all working just exactly the way you want it, do a complete (verified) backup.
